Patent ES-337850-A1 (ES)
Title: Timed switch-control device
IPC: H01H50/88
Filed: 1967-03-10
Abstract: Time-delay auxiliary contacts are provided by a device for attachment to the side of a contactor (F, Fig. 1, not shown), for example, that disclosed in Specification 1,083,711, such that a moving part (G) can engage the protruding end E 1 of a slide E of cruciform cross-section guided in recesses in a supporting bracket member A and a transparent cover D. Slide E carries a contact bridge 10 supported thereon by S-shaped blade springs (9, Fig. 6, not shown) for snapaction change-over between fixed contacts (12). A part 16 carried on slide E co-operates with the centre 18c of a diaphragm 18 to form a valve normally held closed by a spring 17. Diaphragm 18 closes a timing chamber 23 moulded in a body B which also has two substantially annular cavities 29 and 33. A wall 30 closes cavity 33 and a resilient member 32 thereon retains a filter 28 across cavity 29. A narrow passage 34 connects cavity 33 to the contact-enclosing space surrounding slide E, which space is vented to atmosphere around the end E 1 . Narrow passages 24 and 25 respectively connect chamber 23 and cavity 29 to a variable air throttle C formed by a fine circular groove (49, Fig. 6, not shown) the effective length of which is adjustable by rotation of a knob 52. When slide E is urged to the right air is forced via valve 16 and the travel of slide E is unimpeded, but on release its return under action of spring 19 (preset by screw 20) is delayed due to air having to enter chamber 23 via passage 24, the air throttle C, passage 25, cavity 29, filter 28, cavity 33 and passage 34. Thus the device works on a virtually closed air circuit and any residual dust is trapped by filter 28, thereby preventing the air throttle groove (49) becoming blocked. By using the appropriate fixed contacts (12) a delayed make or break is provided as desired, and by fixing the device on the appropriate side of contactor F the delay may occur on release or energization of the contactor.

Title: Cross-linked urethanes and ureas
IPC: C08G73/04
Filed: 1967-03-18
Abstract: Wood, leather, textiles, paper, cellulose, and metals may be coated with a solution in an inert organic solvent of a polymer prepared by reacting an isocyanate terminated prepolymer with an N-substituted ethylene imine, the N-substituent of whichcontains hydrogen atoms reactive with NCO groups, in an amount equivalent or slightly more than equivalent to the NCO groups and cross-linking this reaction product suitably by addition of an acid, an alkylating agent, a # - chloro ethyl urethane or simply by heating. In Examples (9 and 10), metal sheets are coated with a reaction product of prepolymer reacted with 1 -amino-3-ethyleneimino-propane in an organic solvent, which reaction product is cross-linked at 150 to 160 C with simultaneous evaporation of the solvent.

Title: Sheet metal edging apparatus
IPC: B21D19/00
Filed: 1967-06-17
Abstract: Edging apparatus, suitable for rolling the edges of regular or irregular shaped sheet or strip workpieces, incorporates grooved edging rolls 166, 122, 170, 196, 186, and 194 (Figs. 1, 2, in plan) between which a strip 252 is passed, the three rolls on either side of the strip being connected together in groups for movement transversely of the strip. The rolls are mounted in a common plane in respective blocks such as 40, 78, Fig. 3, the outer blocks in each group of three being pivoted to the central one and being adjustable by screws 68 or 96 against spring bias. The lefthand blocks are biased towards the strip by springs 144, while the righthand blocks are adjustable by a screw 200 and hand wheel 206. The roll 122 is driven by a motor 146 through a clutch 154 and chain drive. Adjustable horizontal entry rolls 242 and 244, and one or more exit rolls 236, together with rollers 253, 255, 257, and 259 guide the strip. For thin strip further rolls 212 and 222, disposed between the rolls 122 and 186, may be employed. The rolls 166 and 196 have V-shaped grooves, rolls 122 and 186 U-shaped grooves, and rolls 170 and 194 further U-shaped grooves of larger radius. The adjustment of the outer rolls relative to the centre one determines the degree of rolling of the strip edges. By suitably removing the outer rolls, workpieces of annular, disc, or irregular shape (Figs. 9-11, not shown) may be rolled, in the latter case one of the rolls being urged hydraulically or pneumatically against the workpiece.

Title: Improvements in or relating to methods of manufacturing components employing a high-energy beam of electromagnetic radiation
IPC: B23K26/18
Filed: 1969-11-26
Abstract: A method of manufacturing components e.g. resistors, thin-film circuits and capacitors comprises providing a carrier body with an overall layer of a material, and a further coating with an absorptive characteristic with respect to a beam of electromagnetic radiation used to burn off required areas of the layer of material. A cylindrical ceramic body 1 has a carbon layer 2 with a varnish coating 3 as the absorptive coating. A laser beam e.g. from a CO 2 laser is then focused to a point 8 on the carbon layer, axial and rotating movement causing a helical groove to be burnt in the carbon. Pigments e.g. BaSO 4 added to the varnish vary its absorption relative to the frequency of the radiation used. Suggested coating materials include silicone polyesterimide alkyd and phenolic resin and polymide varnishes. The method is said to be suitable for metal, metal oxide and glaze layers or thin non-metallic layers e.g. insulation.

Title: Hand loom
IPC: D03D29/00
Filed: 1975-03-07
Abstract: A hand loom has a support formed with a multiplicity of parallel guides. A plurality of elongated parallel needles of a first group are each longitudinally slidably received in a respective guide and are each formed at one end with a hook and at the other end with an eye. A second group of similar elongated parallel needles is interleaved with the first group and these needles are also each received in a respective guide of the support. A first holder releasably grips the needles of the first group and a second holder releasably grips the needles of the second group so that each of these groups can be longitudinally slidably displaced in the holder relative to the other group. The hooks of the one group are advanced beyond the hooks of the other group and a weft filament is laid over the advanced hooks that are then retracted to draw this filament under the needles of the other group. Then the weft filament is laid back over the projecting needles of the other group and so on to form a weft on the needles. A warp filament is then threaded through the eye of each needle and as each needle is withdrawn it pulls the warp filament through the weft.

Title: Inspection machine memory
IPC: B07C5/36
Filed: 1976-07-28
Abstract: An improved memory for a glass container inspection machine. In one common form of glass container inspection machines, the containers are indexed through multiple stations where they are inspected for various attributes. Rejection of defective containers can take place only after all of the inspections have been made. The information relative to a defective container is placed in a master-slave type flip-flop uniquely associated with a particular inspection station. Information is then shifted through a group of series-connected master-slave type flip-flops in synchronism with the movement of the container until the container, if defective, reaches a location where it can be rejected. The information is moved or clocked by a generated clock pulse that has a rise time that is faster than the information transfer time through the flip-flops.
